Through the threaded connection of the threaded sleeve 7 and the threaded lead screw 8, the rapid adjustment of the first side board 2 and the second side board 12 is realized. When the first side board 2 and the second side board 12 are adjusted to form a ninety-degree angle with the main board 1, the threat of flying stones from the front and both sides can be significantly reduced, providing more comprehensive protection for on-site operators. The main board 1 is fixed to the ground through a first rivet 19 and a second rivet 21, enhancing the stability of the protection device and ensuring that the protection device will not move or collapse due to vibration or impact during blasting.

[0025] A damper 14 is fixedly connected to the main board 1, a protection board 16 is fixedly connected to one end of the damper 14, a spring 15 is fixedly connected to the protection board 16, one end of the spring 15 is fixedly connected to the main board 1, a second sound insulation layer 17 is provided inside the protection board 16, a protection layer 18 is provided on one side of the protection board 16, a first rivet 19 is provided at the bottom of the main board 1, a support frame 20 is fixedly connected to one side of the main board 1, a second rivet 21 is provided at the bottom of the support frame 20. The material of the first sound insulation layer 3 is foam aluminum, the material of the second sound insulation layer 17 is foam aluminum, the material of the protection layer 18 is rubber.

The rubber protection layer 18 outside the protection board 16 has good elasticity and buffering performance. When the flying stones generated by blasting hit the protection board 16, the rubber layer can quickly absorb and disperse these impact energies, reducing the damage to the protection board 16 and the structure behind it.

[0026] Working principle: When using the blasting safety protection device for mining engineering, the staff first fix the main board 1 to the ground at the blasting safety distance through the rivet one 19 and the rivet two 21. Then, turn the handwheel 13. The handwheel 13 drives the threaded sleeve 7 to rotate on the connecting block one 6. The threaded sleeve 7 drives the threaded lead screw 8 to move through threaded connection. The threaded lead screw 8 drives the connecting block two 9 to move. The connecting block two 9 drives the cylinder two 10 to move. The cylinder two 10 drives the fixed block two 11 to move. The fixed block two 11 drives the second side plate 12 to rotate on the main board 1. At the same time, through the threaded driving effect of the threaded sleeve 7 and the threaded lead screw 8, the connecting block one 6 moves towards each other. The connecting block one 6 drives the cylinder one 5 to move. The cylinder one 5 drives the fixed block one 4 to move. The fixed block one 4 drives the first side plate 2 to rotate on the main board 1. Stop turning the handwheel 13 when the first side plate 2 and the second side plate 12 on both sides of the main board 1 are adjusted to form a ninety-degree angle with the main board 1. In this way, the threat of flying stones from the front and both sides can be significantly reduced, providing more comprehensive protection for on-site operators. Moreover, the front end of the main board 1 is connected with a protection board 16 through a damper 14 and a spring 15. The buffer effect of the spring 15 and the damper 14 can reduce the impact force generated when the flying stones hit the protection board 16. In addition, a protective layer 18 is provided on the outer side of the protection board 16. The material of the protective layer 18 is rubber, which has good elasticity and buffering performance. When the flying stones generated by the blasting hit the protection board 16, the rubber layer can quickly absorb and disperse these impact energies, reducing the damage to the protection board 16 and the structure behind it. Sound insulation layers two 17 and sound insulation layers one 3 are provided inside the protection board 16 and inside the first side plate 2 and the second side plate 12 respectively. The materials of the sound insulation layers two 17 and the sound insulation layers one 3 are foam aluminum, which has excellent sound absorption and sound insulation performance and can quickly absorb the impact sounds generated by impact objects such as flying stones, thus protecting the surrounding environment and personnel safety.
